United States Patent GASEOUS HEATER Joseph S. Fagan, Inglewood, Calif.Application January 22, 1952, Serial No. 267,657 1 Claim. (Cl. 158-53)My invention relates to a gaseous heater of simple inexpensiveconstruction, and adaptable for use in converting liquid fuel into gasand utilizing same as fuel in the development of heat, to be used forvarious purposes.

My invention consists in a stationary chambered member which receivesthe liquid fuel which is converted into gas within a heating tube, saidchambered member being adjustably mounted on said heating tube, withmeans for controlling the admission of air into said tube and saidburner being adjustable within said tube so as to vary the degree ofgenerated heat.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangement of partshereinafter more fully described,

claimed and illustrated in the accompanying drawing, in

which:

Fig. 1 is a plan view of a gaseous heater constructed in accordance withmy invention,

Fig. 2 is a longitudinal section taken on the line 22 of Fig. 1,

Fig. 3 is a cross section taken on the line 3-3 of Fig. 1,

Fig. 4 is a cross section taken on the line 44 of Fig. 1.

Referring by numerals to the accompanying drawing, designates a heatingtube, open at both ends, and provided at its rear end with ahorizontally disposed U-shaped frame or support 11. Adjustably mountedat the center of said frame, and adapted to be secured thereto by a setscrew 12, is a burner tube 13 which extends axially into the heatingtube 10, and its forward end being provided with slots or apertures 14which serve as jet apertures for the gas as it discharges from saidtube.

Adjustably mounted on the side members of frame 11, adjacent the rearopen end of the heating tube 10, is a plate 15 which serves as a damperfor the air entering said tube, and the edges of said plate are notchedas desig nated by 16 at diametrically opposite points, for reception ofthe arms of the frame 11.

Formed on plate 15 is a collar 17 carrying a set screw 18, used forlocking the damper to burner tube after adjustment. Arranged forlongitudinal adjustment on tube 10 is a chambered tubular member 19,considerably shorter than said tube and said member 19 is slightlyspaced apart from'said tube 10 by means of thin narrow lugs 20 formed onthe inner face of said member adjacent its ends.

A liquid fuel supply pipe 21 provided with a valve 22 is connected toone side of chambered tubular member 2,693,229 Patented Nov. 2, 1954 19and connected to the opposite side thereof by a fitting 23, 1s a gasconducting pipe 24, which is connected by a fitting 25, to the outer endof the burner tube.

Pipe 24 is provided with an intermediate loop 26 which gives suificientflexibility to enable burner pipe 13 to be adjusted lengthwise in theheating tube 10.

In service, valve 22 is opened to permit liquid fuel to flow throughpipe into the chambered member 19, which, when heated, gasifies saidliquid fuel and a portion of the gas passes through flexible tube 26, toburner tube 13 and upon being ignited, the burning gas heats tube 10 andwhatever work is placed immediately adjacent thereto. Damper 15 may beadjusted toward or away from the end of heating tube 10 to control theadmission of air thereto and burner tube 13 may be moved into or fromsaid heating tube so as to regulate the degree of heat imparted thereto,and to the chambered tubular member 19 in which the gas is generated.

Thus, it will be seen that I have provided a gaseous heater that issimple, strong, durable, of inexpensive structure and which is veryeffective in performing the functions for which it is intended.

Minor changes in the size, form and construction of the various parts ofmy improved gaseous heater may be made and substituted for those hereinshown and described, without departing from the spirit of my invention,the scope of which is set forth in the appended claim.

I claim as my invention:

In a gaseous heater, a heating tube open at both ends, a chamberedmember arranged for sliding movement the entire length of said heatingtube, lugs projecting inwardly from the end portions of said chamberedmember and bearing upon. the heating tube, so as to maintain saidchambered member in spaced relation upon said tube, a liquid supply tubeleading to said chambered member, an integral U-shaped frame projectingfrom one end of said heating tube, a burner tube adjustably mounted insaid U-shaped frame and extending axially into said heating tube, meansfor securing the heating tube to said frame, a damper slidable upon saidburner tube and said frame, means for securing said damper to the burnertube after adjustment, and a tube connecting the chambered member to theouter end of said burner tube and which last mentioned tube is providedintermediate its ends with an extended loop.
